The leverlO is likethrough vice herein, which'will berecognized as extremely simple,

easily operated and not liable to become deranged or out of order.

I will now takeup the description of the thermostatic portion of mydevice, such being required to actuate said regulatorthe instrumentalityof the greater or lesser degree of heat in the heater portion of thefurnace. This thermostatic device is composed of a vertical rod 23,a'vertically-adjustable fork 24 having screwthreaded connection with asocket in the upper end ofsaid rod, a hollow or open mouthed contacthead25 having adjustable screw-threaded connection with the lower end ofsaid rod, a lock-nut 26 for said eontact-head 25, and a detachable panor receptacle 27 carried by said rod 23 between its upper and lowerends.

theholes 16 at the outer end of the lever 10, said holes 16 beingadapted to furnish.

any variations in the assembling of the parts of my device for use. Thecontact-head 25 at the lower end of the rod 23 is provided by me for thereason that its lower edge is of greater area than that of the roditself would be'and such greater area enables an increased contact, aswell as a surer contact with the upper surface of the crown or dome ofthe heater, as best seen in Fig. 3. The open mouthor hollow of thecontact-head 25' encircles the small nipple or projection 28. thatcustomarily tips'the dome-of an ordinary furnace heater. projectionserves as a guide or centralizer for suspending the thermostatic portionof my device over the heater and does not interfere with its operation.The pan 27 forms a receptacle into which a quantity of sand or otherlike convenient matter is placed to provide a variably-disposed weighton the rod 23 and, also, on the regulator lever 10 to suit the desiredadjustment of the entire device. Said pan is detachably secured on saidrod by means of a set-screw 27 or the like.

In order to more conveniently use the furnace with my improved regulatordevice, I provide a very simple connecting-means with an indicator 36that is located in the apartment above the cellar or basement where thesaid furnace is located. Such connecting-means is composed of a pair ofangular-levers or bell-cranks 29 pivotally mounted at the respectiveopposite ends of the timber or bar 13, (as best seen in Fig. 1,) aconnecting-wire or rod 30, a chain or flexible connection31 leading overa pulley 32 from one of the bell-cranks 29 through an opening 33 in thefloor 34 to said indicator the said pinion, in turn,

The upper forked end 2 1 is detachably secured in either one of so as tofrequently Said nipple or" mounted. on said bell-cranks 29, over whichpulleys the chain 21 is hung and rides in the opening and closing of theseveral air valves 7 and 9 to suit thecondition of the heat radiatingfrom the furnace 1 and the expansion and contraction of the latter inuse.

. In the operation of my improved regulator device, the expansion of thefurnace due' to the heat within causes the rod .23 to rise, therebyactuating the lever 10, the latter, in turn, moving downward at itsarc-formation 15 end and causing the pinion 17 toturn;

causes the crankarm 19 to move, whereby the chain 21 rides along thepulleys 35 against the heft of' the weight 22 and allows the draft-lid 9to gravitate gradually and slowly toward'the draft-opening 8 for closingor otherwise limiting the amount of air passing into said 0 ening 8,and, also, raising the check lid or amper 7 for admitting air to thesmoke pipe or flue 4; the" said lids or dampers 7 and 9 alternatelyclose and open to suit the amount of 'air to pass into the flue or intothe draft opening, as occasion may require in the regulating of thefurnace for greaterv or less heat, or uniform heat in' the apartmentsabove; the indicator 36 in the apartment above will show thereon justwhat position the regulator and the dampers are in,

save the operator a number of trips to. the basement or cellar belowwhere the furnace is ishing of, or other attention to the fire-and thefurnace. The weight 22 serves to automatically return the damper 7 toclosed or closing position and to raise the draft-lid 9 to open positionwhen the toothed sector 15 has moved upward and, also, when thethermostatic device has returned to its downward position ready foraction upon even the minutest expansion of thedome of the heater.

I claim 1. In a heating apparatus having air check and draft valves, aregulator device comprisinga pivotally hung lever havin a toothedarc-formation at one end thereo a 36 in said apartment above. Pulleys 35are located in the replen pinion journaled in co-acting relation withrod, a variably-connected fork provided at actuating-armplvotally-mounted in relation with the heating apparatus andvariablypansion and contraction of the contacting part of the heatercauses the desired movements of 'said actuating-arm of the regulator.

3. In a heatingv apparatus having air check and draft devices, a thermaldevice I flexibly-connected tov said air check and draftdevices andhaving at its lower end an open-mouthed contact-head adapted to engagethe tip oflthe heater dome, a variablyattached fork at the-upper end ofthe rod forming a part of said. thermal device, a Weight pan or recetacle carried by said rod and adapted to re eive sand or other loosecontents capable of variable heft therein.

4; In a furnace-regulator, the combination with an arm or lever carryinga toothed arc-formation at one end thereof, a pinion engaging saidarc-formation, a crank-arm connected with said fork, whereby theexconnected to said pinion to coiipe'rate therewith, a flexible deviceconnected vto said crank-arm and riding over suitable pulleys forconnection at its opposite ends with the air check and draft dampers ofthe furnace,

bell-cranks carrying said pulleys, a rod connecting said bell-cranks, aflexible connection between one of said bell-cranks and a suitableindicator located in the apartment above the chamber occupied by saidfurnace and thermal means between said arc-formation-lever and theheater for-actuating both 3 the regulator and the indicator.
